DE2516921A1 - Cutter for removing round clod of earth with plant - comprises two wedge-shaped cooperating blades which are curved in two planes - Google Patents

Abstract

The cutter is for shaping and removing a spherical clod of earth together with a plant which is to be transplanted, and, comprises two shaped blades curved both in the horizontal and vertical directions and secured together by a common bearing which effects radial movement when actuated by a lever assembly, the blades overlapping when closed. The lever assembly comprises a lever attached on each side above the bearing at an angle of 75 deg.ends of the two levers are pressed outwardly, causing the blades to move radially into the soil.

Description

Bale cutter for plants Area of application: to The device is used for cutting out or shaping a spherical ball of earth in plants, which are firmly rooted in the earth - especially for commercial horticulture - purpose: So that after a replanting a safer growth of the plants is guaranteed, these are excavated with a ball of the earth from their previous site.

state of the art: In order to produce a ball of the earth, the plant pierced with a spade in a circle and then lifted out of the soil.

In the case of large solitary plants (avenue trees, etc.), this is already used hydraulically driven grippers are used.

Then the now still misshapen brdhallen with your hands or a spade into a spherical shape and wrapped in a cloth.

Critique of the state of the art: The piercing with a spade is cumbersome and time consuming. Likewise, if you are working on your own, a uniform shape or

-Sizing of the ball of the earth cannot be achieved.

A uniform shape of the ball of the earth is also with the previously constructed, hydraulically driven grabs have not been achieved as these are a Do not cut off a large part of the root system, but rather when lifting the plant up from the earth and thereby damage the teeth.

Task: The invention is based on the task of stitching with to spare the opate and the shape of the balls, which are evenly large and spherical to manufacture.

Solution: The object is achieved according to the invention in that when removing the plants from the ground, the bale cutter only applied once are needed and when retracted by the pliers-like radial movement of the circular arranged cutting knife cuts out a form-fitting bale.

Further embodiment of the invention: As when using the device a uniform shape of the brdballens is guaranteed, there is now the Possibility of wrapping the ball in a ball cloth, which was previously necessary a better practice to replace it. Preformed cloths or Vessels come into use.

Achievable advantages: The advantages achieved with the invention exist in particular that for the production of a ball the piercing with a Spade is replaced by the use of the device.

This allows the work to be done faster and even by inexperienced workers are executed.

Furthermore, a uniform shape of the bale is guaranteed.

Description of the exemplary embodiments: The two octmeid knives are on one side by a common bearing, which also causes the radial movement, held.

According to this radial movement, the knives have the shape of a Section of a circle or section of a sphere; i.e. they are horizontal as well as vertical formed circular.

To easily penetrate the earth ozw.

To achieve a flawless cut, the knives are towards the middle wedge-shaped and sharpened. The wedge shape is designed so that the esser overlap when shearing lamb scissors. On the opposite side of the camp are both knife ends shortened so that the above-ground one at this circular opening Part of the plant (stem) can be encompassed by the cutting knives. About the camp, which one of the two cutting knives serves is in an angular position of Approx. 75 @ a firmly welded HeDelarm attached. When pressure is applied from above, the both lever arms left and right pressed down and thus the cutting knife led radially into the earth. In order to achieve a uniform ball depth, it must Device can be inserted into the earth to the desired depth. This depth can by an arbitrarily adjustable iuerstück, which is located at the lower end of the guide shaft (Pipe or profile iron) is to be fixed. with larger devices it would be It is advantageous to equip this piece with two wheels, which not only fix the depth but also make it easier to transport the device.

The drive or the power transmission for the fferunterarücken two lever arms on the cutting knives are used for small plant balls by a Foot pedals enabled. This foot pedal is equipped with a sliding tube (or profile iron) connected, which slides up and down on the guide shaft of the device.

In turn, 2 lever arms are held in a bearing on this guide tube, the other probes left and right with the cutter lever through each one Bearings are connected. When you step on the foot pedals, the sliding tube is pressed down and both lever connections spread apart or the cutter in the Earth pressed and closed.

To open the cutter, a handle is provided that goes through a rod is connected to the sliding tube. When pulling this handle into the in the opposite direction, the device is brought back into its starting position.

For larger bales of plants, instead of the foot force, the foot pedals apply acts, a jackhammer or other vibrating device, which is attached to the guide shaft with sliding up and down, can be used.

For large bales there is one via motor and gearbox or one hydraulic Power transmission can be used.

Claims (1)

Patent claims Generic term: earth ball cutter for shaping and removing Balls of earth on plants, in particular for commercial horticulture. Characteristic part: Characterized by the shape of the two cutting knives and their radial movement as well as by the actuation mechanism. Generic term of the sub-claim: Improved method of charging interest the ball into a ball of cloth through the even ball shaping that can now be achieved. Characteristic part of the dependent claim: characterized in that there is a possibility of avoiding wrapping the bale in a nall cloth and to be replaced by any pre-formed cloths or vessels.
